Benzene Is A Carcinogen Found In Gasoline / Chemical Safety PSA
Benzene Is A Carcinogen Found In Gasoline / Chemical Safety PSA. Public domain video courtesy of NIH.
Gasoline contains benzene, depending on the source of gasoline, and countries, ranges of concentration of benzene in gasoline have been reported as 1 to 6%. Gasoline is also used as an industrial solvent and workers commonly experience inhalation and skin exposure. In my practice, it is not unusual to hear from workers that “I washed my hands with gasoline to remove paint daily” or “the smell was so strong that I got dizzy”, demonstrating substantial exposure to gasoline ongoing on a daily basis. Since benzene is a known human carcinogen, it would be expected that gasoline will be also a hematopoietic toxic and cancer causing agent as well. Indeed, Aksey et al as early as 1928 reported aplastic anemia, and in 1941, Machele et al reported thrombocytopenia from gasoline intoxication. Other hematopoietic malignancies have been reported as a result of gasoline exposure. Epidemiological studies of workers and filling station attendees have shown genotoxic effects at very low benzene from gasoline vapor exposure. Brandt et al have demonstrated genotoxic effects in workers exposed to low levels of benzene from gasoline. Santos-Mello et al have shown chromosomal deletions in lymphocytes of workers exposed to gasoline as attendants. Infante et al reported hematopoietic malignancy in petrol exposed workers. Similar exposures to gasoline in garage mechanics and filling stations have been reported. What are the health effects of exposure to gasoline vapors? Gas cans emit pollutants such as hazardous air pollutants (HAP) and volatile organic compounds (VOC). These pollutants can contribute to health problems that may affect homeowners, their families, and the community. VOC can produce ozone, which may cause respiratory problems for those with cardiac or respiratory diseases. Chemicals in these substances can also react in the air to form ground-level ozone (smog), which has been linked to a number of respiratory effects. EPA has developed a Web site related to ground-level ozone. Benzene: Exposure to benzene may cause irritation of the skin, eyes, and upper respiratory tract as well as blisters due to dermal exposure. Long-term exposure to benzene may cause blood disorders, reproductive and developmental disorders, and cancer. EPA has collected extensive information on the health effects of exposure to benzene. When gasoline vapors collect in a closed environment such as a non-ventilated shed or garage, the potential for an explosion increases. Benzene is an aromatic hydrocarbon that is produced by the burning of natural products. It is a component of products derived from coal and petroleum and is found in gasoline and other fuels. Benzene is used in the manufacture of plastics, detergents, pesticides, and other chemicals. Research has shown benzene to be a carcinogen (cancer-causing). With exposures from less than five years to more than 30 years, individuals have developed, and died from, leukemia. Long-term exposure may affect bone marrow and blood production. Short-term exposure to high levels of benzene can cause drowsiness, dizziness, unconsciousness, and death.

EnCana Buries Hydraulic Fracturing Pit Sludge in Unlined Pit May 14, 2009
Twenty-three days after EnCana completed hydraulic fracturing operations on the F11E, the liner is removed, some of the sludge is pumped out and the remainder – perhaps 70 barrels or more – is dozed in.
The pad overlies a spring that often surfaces here. It is fed by a shallow groundwater aquifer that supplies water to West Divide Creek and a family’s private water well located maybe 200 yards away. An irrigation ditch is located approximately 30 feet from the East end of the pit.
If one of the pumper trucks had overturned on the county road, spilling this stuff into the environment, a hazardous materials unit would have responded, sequestered the area, potentially evacuated citizens and employed measures to safeguard first responders, citizens and the environment. But because this is a hydraulic fracturing waste pit, out of sight of the public and on private land (owned, coincidently, by EnCana) it is simply covered up.
This same site – if it were at a gas station or a paper mill or a chemical manufacturing plant – would likely be a violation and require extensive clean-up and proper disposal at a licensed facility… as it should. But, again, here, in rural Garfield County, it is simply buried.
Industry would like us to believe that frac fluids are merely salt water, a little thickener, and food additives. But we know frac mixtures contain all kinds of hazardous substances, like biocides, benzene, hydrocarbons, solvents, descalers, surfactants, enzymes, acids, and patented synthetic chemicals. We also know the adverse health effects of some of these agents.
We know a nurse in Durango, CO nearly died of catastrophic organ failure after unprotected exposure to fracturing chemicals (we don’t know what happened to the field worker she cared for). We know her physician had to guess how to treat her as she lay dying. And we know that industry lawyers blocked her testimony at a rules reform hearing where citizens and advocacy groups were lobbying for chemical disclosure. We also know that the oil and gas industry has totally refuted her claims in literature distributed to lawmakers in Washington, DC intended to influence legislators against voting to repeal hydraulic fracturing from the Safe Drinking Water Act.
Watching a bull dozer blade this toxic brew beneath twenty feet of uncontained soil is horrifying. Knowing that this industry is allowed to poison the land, the water and the people is even worse.
Eventually this pit was completely covered.
This site is less than a half mile from my home…. a place in the Rocky Mountains now exploited for its natural gas resource. A place once rich in other resources as well… water – air – land – wildlife – community.
EnCana calls where I live their “Field of Dreams”. As they abuse the ecosystem and destroy its fragile sustainability, they reap a finite reward while leaving behind an industrial waste dump.
I apologize for the shaky video and loud background noise. The wind was blowing so hard it was shaking my hand and totally flooded the microphone.
Despite the awful nature of this situation, the meticulous work conducted by the dozer and excavator operators was something to see. I knew an operator who competed in heavy equipment rodeos, and watching him excavate was amazing.
All the folks on this site seemed capable, and I doubt that any of them gave a second thought to burying this pit. Field workers have told me this is common practice. They probably had no idea it was right over an aquifer and never considered the effects on a stream or private water well. They work around this stuff all the time, and many come to consider it routine, even unknowingly putting their own health at risk. But, EnCana leadership is well aware, and that is where accountability must begin.
As with most of these situations, it is the underlying structure of inappropriate federal exemptions, weak state rules and poor but accepted practices that lead to making this the terrible situation it is.
Only with full accountability can we develop workable and mutually beneficial solutions. Which are more than possible – they are at the leading edge of demand and on the precipice of necessity.
Ultimately, the fossil fuel industry must come out of the dark ages and embrace a more honest and cooperative manner of conducting their operations.
Part of that involves repealing exemptions that allow and encourage them to operate like a lawless regime, putting human health and safety as well as the environment at frequent and serious risk.
For over a year, at www.journeyoftheforsaken.com, I’ve been documenting EnCana’s aggressive and irresponsible development of 60 natural gas wells around our home and the infamous area of the 2004 West Divide Creek natural gas blowout.
